Abstract
An electrically isolating gasket is disclosed wherein a coating layer is disposed on at least one conductive surface, and in some embodiments, on all surfaces or at least all of the conductive surfaces. The electrically isolating gasket includes a core gasket component, a ring seal component, and a non-conductive inner seal component. The coating layer can be, for example, polyimide, polyamide, ceramic, and aluminum oxide.
Claims19
An electrically isolating gasket comprising:
- a metallic gasket core, the metallic gasket core having a disc shape and including radially extending opposed faces separated by an axial height and an inner core surface extending along the axial height between the opposed faces having a first, non-linear shape;
- and
- a non-laminated coating bonded to the radially extending opposed faces, wherein the non-laminated coating comprises a dielectric material formed on the opposed surfaces of the metallic gasket core by being applied to the metallic gasket core in a liquid form and then cured to form a solidified coating, and
- wherein the metallic gasket core comprises at least one groove in each of the opposed surfaces and where the non-laminated coating is bonded to at least one surface of the at least one groove in each of the opposed surfaces.

A method of manufacturing an electrically isolating gasket comprising:
- providing a retainer wherein the metallic gasket core is formed from a conductive material, the metallic gasket core having opposed axial faces and a concave shaped inner core surface;
- coating every surface of the retainer, including the concave shaped inner retainer surface, with a liquid coating comprising a dielectric material;
- and continuously curing the liquid coating to harden the liquid coating and bond the coating to the retainer without lamination, and
- wherein the metallic gasket core comprises at least one groove in each of the opposed surfaces and where the non-laminated coating is bonded to at least one surface of the at least one groove in each of the opposed surfaces.
